The gcrnis Sabia was first described by Colobrooko* in the year 1820, with a
aomewhal erroneous generic Hiarai'ier, and a plate \\liidi neenratcly represents the
habit ami general aypenraueu of the ]>liint, but is ancotnpanieil by a very imperfect
figure of the ilowcr. In 1S-4, AValliehf published excellent descriptions'of two ad-
ditional species, giving \\\ the same time a corrected generic character, and referring
the genus to TurGbitit/uwftr. In 1825, Itluiue,:); unaware of what had previously
been done, added another speeies under the generic name Memscosta, which he
placed at the end of Me?rispei'mace(e. Endlioher and JMeisner, adopting "Wallich/s
suggestion, placed Sabia at the end of AnaraTttiacea?. In 1842, Falconer§ published
an excellent account of the genus, under tbo name of 7vV'#//'//, which he indicated as
the type of a distinct Order, pointing out the resemblance of the fruit to Memsyer-
macetp9 but not pronouncing definitely on its affinities. In 1831, Blumc,[| who had
discovered the identity of^jfer'genua Jlle.mcosfa with XaAit/i eonxtituted the Natural
Order Su&iticfff* the place of \vliieh he fixed in the immediate viciuify of Menisper-
wacete; and in Ib53 MjerR*. adopted that Natural Order, taking the same view of
its affinities. He has, however, fallen into an error in describing the ovules as soli-
tary, and has overlooked the remarkable character of the opposition, of the jxitals and
sepalrt.

The structure of the genus Sabia is so remarkable, that its claims to form a dis-
tinct Order are unquestionable; but, as in the case of many Orders of limited extent,
the characters point in so many different directions that-it is not easy to determine
the position which it ought to occupy in our systems. If the ovary of Saliacea be
considered synearpous, the presence of a well-marked" hypogynous disc, and many
other characters, would seem to indicate the Rhamnal alliance as that to which they
are most nearly allied. Among its Orders, CAattMiaccte, which have n two-celled
ovary, containing two collateral pendulous ovules in eae.h cell, a simple style, and
exalbuminous seeds, appear to exhibit the greatest amount of resemblance to Sabiacea.
There are, however, many obvious differences, such as the structure of the petals, the
drupaceous fruit, and the curved embryo with inferior radicle, and thid affinity is
prooably"a distant one.
